This is actually a double idea :
- Provide a native iOS/Android application to be used purely as an interface with possibilities to interact with your wallet (probably through metamask or wallet connect).
This is in my opinion a good idea, although we would probably need to wait a tiny bit of time for the v2 interface to be fully up and that way start working on the latest version
- Provide a Traditional Financial infrastructure (or bridge) between Fiat and Crypto, using Yearn as a passive Yield generator and enabling users to onramp from fiat to Yearn back and forth directly from an app.
This, in my opinion, it is not Yearn’s core purpose as of today, and more than that, it’d require the Yearn DAO to start being a legal entity in a country, which is again, not Yearn’s purpose IMO.
So basically, as I am 100% for a Yearn phone app, that would allow simpler use of the yearn products accros more devices, I believe this should be an interface to the Yearn products and it’s partners products.
However, about the fiat-to-crypto bridge, I believe it should be done by integrating yearn into apps or services which business is based in being a bridge. This could be Zerion / Zapper (if they ever build a native app) and other DeFi analytic’s app such as DeBank.
This could also be true for brokers that offer interest services, such as SwissBord, that has a Yield Wallet feature for USDC that generates interests but which main business is trading cryptocurrencies.
Finally, the best idea IMO would be to integrate even further with Smart Wallet providers such as Argent or Dharma because they already started integrating with DeFi projects so their framework is done and adding or removing projects becomes frictionless for them and as a Social Recovery Wallet, they beat centralized brokers like SwissBorg in the sense that the user is still in control of their keys and they already have the financial infrastructure in place, or nearly in place, to enable a fiat-to-crypto bridge. (Vitalik made a blog post about it : here).
